Knowledge, Attitude and Practice of Dental Practitioners towards Screening for Oral Pre-Cancer and Cancer

One of the global health issues is Oral cancer, which has an increased death rate. Awareness of oral cancer screening is important for oral health care professionals for early detection and improving the patients' survival rate. Attitude towards oral cancer awareness and knowledge of oral cancer screening are the key factors that impact oral cancer awareness success. Materials and Methods: To assess the knowledge, attitude, and practice of dental practitioners and dental students towards screening for oral pre-cancer and cancer. This study included dental practitioners working in various academic institutions and private practitioners in Chennai. Participants were asked to fill in age, gender, designation, and experience. A structured questionnaire consisting of 10 questions, each having four options, was administered to the participants. The data collected was 100 responses analyzed by statistical package for the social science (spss inc., version 16 for, Chicago, IL, USA). Simple descriptive statistics were used to describe the distribution of data collected. T-test and ANOVA were employed to assess the statistically significant difference in the KAP scores between different groups. Results: The response rate for the present study was 100%. 37% of general dental practitioners reported that they routinely do a thorough oral examination for all the patients,52% agree that they are adequately trained to examine patients for oral pre-cancer and cancer screening,8% of them reported that they never do toluidine blue staining for patients with oral lesion. Majority(57) of them agree that they would recommend biopsy for suspected cases of oral cancer. Only 9% of the participants were aware of the time required for intraoral screening examination. 31% of them were aware of the risk of malignant transformation in a white lesion. 73% of the participants were aware of the occurrence of oral cancer in non - tobacco users was rare. 53% of agree that thorough intraoral examination for oral cancer will reduce oral cancer mortality and morbidity.

Artificial Intelligence in Diagnosis of Oral Potentially Malignant Lesions- Need of the Hour

Artificial intelligence (AI) is a technological breakthrough that is rapidly progressing and has captivated the minds of researchers all over the world. AI can be used to make a diagnosis of oral cavity lesions, detect and identify suspicious changed oral mucosa undergoing premalignant and malignant transformations. The purpose of this review is to give a comprehensive summary of developing optical imaging technologies, innovative artificial intelligence-based techniques. The concepts of image-based techniques for identifying oral cancer are defined in terms of clinical requirements and features. Although artificial intelligence (AI) is beginning to have a significant impact on increasing diagnosis accuracy in a variety of fields of medicine, there has been limited research on oral cancer to date. These results suggest that combining artificial intelligence with imaging can improve oral cancer outcomes, applications ranging from very low-cost oral cancer screening with Smartphone-based probes to algorithm-guided identification premalignant lesion heterogeneity and margins using optical coherence tomography. Oral cancer outcomes can be improved by combining imaging and artificial intelligence technologies for better detection and diagnosis.

Validity and Reliability of Intraoral Camera with Fluorescent Aids for Oral Potentially Malignant Disorders Screening in Teledentistry

There is limited documentation of using fluorescence images in oral potentially malignant disorders (OPMDs) and oral cancer screening through the field of teledentistry. This study aims to develop and evaluate the validity and reliability of the intraoral camera with the combination method of autofluorescence and LED white light used for OPMDs and oral cancer screening in teledentistry. The intraoral camera with fluorescent aids, which uses a combined method of both autofluorescence and LED white light, was developed before the device was evaluated for validity and reliability as a OPMDs screening tool for teledentistry. All lesions of thirty-four OPMD patients underwent biopsy for definitive diagnosis and were examined by an oral medicine specialist. Both images under autofluorescent and LED white light mode captured from the device were sent online and interpreted for the initial diagnosis and dysplastic features in addition to being compared to the direct clinical examination and histopathological findings. The combination method was also compared with autofluorescence method alone. The device provided good image quality, which was enough for initial diagnosis. Using the combination method, sensitivity, specificity, PPV, and NPV of the device via teledentistry were 87.5%, 84.6%, 63.6%, and 95.7%, respectively, which were higher than autofluorescence method alone in every parameter. The concordance of dysplastic lesion was 85.29% and 79.41% for category of lesion. The validity and reliability results of the combination method for the screening of dysplasia in OPMDs were higher than autofluorescent method alone. The intraoral camera with fluorescent aids for the OPMDs screening can be utilized for screening via teledentistry.

Pilot Model for Community Based Oral Cancer Screening Program: Outcome from 4 Northeastern Provinces in Thailand

Management of advanced-stage oral cancer adds a great burden to individuals and health care systems. Community-based oral cancer screening can be beneficial in early detection and treatment. In this study, a novel oral cancer screening program was conducted utilizing an existing network of health care personnel, facilities, and digital database management for efficient coverage of a large population. The screening program considered 392,396 individuals aged ≥40 from four northeastern provinces in Thailand. Three levels of screening were performed: S1 by village healthcare volunteers to identify risk groups, S2 by dental auxiliaries to visually identify abnormal oral lesions, and S3 by dentists for final diagnosis and management. A total of 349,318 individuals were interviewed for S1, and 192,688 were identified as a risk group. For S2, 88,201 individuals appeared, and 2969 were further referred. Out of 1779 individuals who appeared for S3, oral potentially malignant disorders (OPMDs) were identified in 544, non-OPMDs in 1047, doubtful lesions in 52, and no results in 136 individuals. Final treatment was carried out in 704 individuals that included biopsies of 504 lesions, exhibiting 25 cancerous lesions and 298 OPMDs. This study is so far one of the largest oral cancer screening programs conducted in Thailand and showed effective implementation of community-based oral cancer screening.

Knowledge & Practices Regarding Oral Cancer among Graduating Dental Students in Bhopal City, India

Background: Evaluation of oral cancer related knowledge among dental students would aid in planning the oral health service programs and curriculum on large scale. The aim of this study was to assess the self reported knowledge and practice pattern of dental students in Bhopal, India. Methods: The study population comprised of 200 dental students studying in final year and undergoing internship. Knowledge and practices were recorded using closed ended assessment form. Simple percentages were calculated to draw inferences. Results: 68% students agreed that their knowledge regarding the prevention and detection of oral cancer is current and adequate. A total of 178 (89%) felt that there is need for additional training/information regarding oral cancer. Almost half 106 (53%) agreed to have you ever attended any educational programs on oral cancers. Conclusion: The knowledge of graduating dental students was found to be adequate. The need for regular clinical updation and practices related to screening cannot be ignored. Keywords: dental students, knowledge, oral cancer, screening, tobacco.
